The 2500kVA and 3150kVA Step-Down Oil-Immersed Distribution Transformers are designed for medium- to high-capacity power distribution systems, providing reliable voltage reduction from 11kV or 33kV to low-voltage levels for industrial, utility, and infrastructure applications.

These transformers adopt a mineral oil–immersed structure, offering excellent heat dissipation and strong insulation performance. The oil-filled design ensures:

• Stable operation under continuous and heavy load conditions
• High resistance to short-circuit and thermal stress
• Long service life with proven reliability

• Rated capacity: 2500kVA / 3150kVA
• Rated voltage: 11kV or 33kV (HV)
• Three-phase configuration
• Frequency: 50Hz or 60Hz (optional)

The optimized core and winding design delivers high efficiency, low losses, and stable voltage regulation, making the transformer suitable for demanding power distribution networks.

• Reinforced windings with high short-circuit withstand capability
• Efficient cooling system (ONAN, optional ONAF)
• Low temperature rise, supporting long-term overload operation

These features ensure reliable performance in industrial plants, substations, and utility networks.

The transformer can be customized to meet specific project requirements, including:

• Vector group selection
• Impedance adjustment
• Tap changer configuration (off-circuit or on-load)
• Special insulation levels or environmental conditions

• Utility and grid distribution substations
• Industrial power supply systems
• Mining, oil & gas, and heavy industries
• Large commercial and infrastructure projects
• Renewable energy grid connection system
